The Nature of the Sharp-lined A1 V Star HR 4138.
MONIER R.
Abstract (from CDS):
The comparison of far-ultraviolet spectra taken years apart with the IUE shows that the FUV flux of HR 4138 is variable. An abundance analysis of High Accuracy Radial velocity Planet Searcher spectra reveals that the light elements (with Z less than 30) have solar or nearly solar abundances whereas heavier elements are overabundant. Inspection of the Transiting Exoplanet Survey Satellite lightcurves of HR 4138 suggests that the rotational period of HR 4138 may be close to 3 days.
